Application filed June 14, 1921; Serial no. 477,529.

To all whom it may concern Be it known that l, JOHN PAsoHALL, a itizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Tm provements in Spraying Machines, of which the following is a specification.

This invention relates to spraying maQ .chines particularly designed for spraying paint, calcimine or analogous material over relatively large-flat surfaces and an object of the invention is to provide a practical device-of this nature by means of which paint or analogous material may be evenly spread in a minimum amount of time and one which is comparatively convenient of operation and will spread the paint in cracks, crevices or inconvenient places in the surfaces being treated.

A further object of the inventionis to provide, in a device as specified a novel nozzle structure by means of'which the quantity anddensity of the spray may be regulated as desired and conditions necessitate.

A further object of this invention is to provide a device as specified which includes a guard to prevent improper scattering of the material being sprayed as well asone which combines in combination with a spraying nozzle, a plurality of brushes arranged to conveniently distribute the material sprayed.

An'otherobject of the invention is to provide a novel construction for connecting the may be varied during the movement of the machine over a surface being treated.

Other objects of the invention will appear in the following detailed description and in the accompanying drawings wherein:

Fig. 1 is a top plan of the improved spraying machine.

Fig. 2 isa bottom plan of the improved spraying machine;

Fig. 3 is a side elevation of the spraying machine. f I i a Fig-.- 4 is a vertical section through the in m ne.

'5- a'deta-il'section through the im- Fig: 6 is a. detail section taken on the line s an "enlarged and view of the Referring moreparticularly to the draw ing the improved spraying machine comprises a main body 1 which is substantially stantial frusto conical guard 2 positioned therein in the vertical .center of which is positioned a paint or material spraying nozzle structure 3. The spraying nozzle structure 3 includes a carrying body 4 which has a lateral ofiset portion 5 at one end in which a needle valve 6 is positioned, the said needle valve being adjustable relative to the outlet opening 7 by means of an adjusting nut 8 through which the stem 9 of the needle valve extends. The adjustment of the nut 8 affects the needle valve and adjusts itthrough the medium of the spring 10, the tension of the spring against the head 11 being regulated by the adjustment of the nut, and the outward pressure of the spring on the head 11 forces the needle valve 6 away from the seat 7. A spring 10 is coiled about the stem 9 and engages at one end against the head 11 on the stem 9 and at the other end against the head 12 of the adjusting nut 8, the said spring serving to permit manual movement of the needle valve 6 if desired for momentary adjustment of the needle valve without adjustment of the adjusting nut 8. The stem 9 has a spiral fluid guide '13 mounted thereon for guiding the fluid in a spiral or swirling path during its passage to the opening 7 for insuring more efiicient spreading of the fluid. The outlet opening 7 is formed centrally Within the outer end 14: of a cap 15 which is removably mounted upon the extension 5 on the body 4: of the nozzle structure. A deflector 16 is mounted about the cap 15 being held thereon by means of a set screw i spreading of which substantially conical sheet of fluid is limited by the deflector 16 and guard 52. By adjustment of the bolt 20 for regulating the distance between its rounded head 21 and the opening 7 the dim.

eter and spreadof the liquid may be regulated as desired. A nut 22 is mounted on the bolt 20 for engagement against the collar 18 to lock the bolt-in adjusted positions.

The body 4 of the nozzle structure 3 has ,a reduced screw threaded sleeve .23 formed thereon w hich serves to connect the nozzle 3 to a coupling 24 carried outwardly of the top 25 of the guard 2. Suitable transverse braces 26 are provided which are attached to the inner surface of the sides of the body 1 and extend across the top of the guard 2 serving to connect the guard to the body 1 and to increase the rigidity of the body 1.

A second coupling 27 is connected to the coupling 24 for rotary movement about an axis transversely of the axis of the nozzle 3 and the coupling 27 is able supply pipe 28 throu h which the liquid or fluid to be distributed by the spraying machine passes. A suitable valve structure 29 of any approved construction is mounted in the combined handle and supply pipe 28 to permit the controlling of the passage of fluid, under pressure, to the spraying ma-- chine. Arcuate guide rods 30 are carried b the body 1 and are sitioned one upon eac side of the combine handle and supply pipe toprevent lateral vibratory movement thereof during operation of the device. Guides 31 and 32, which also serve as. braces, are connected to the combined handle and supply pipe 28 by means of the clamping structures 33 formed upon their endsand they extend between plates 34 and 35a pair of which is itioned at opposite sides of the body 1. he plates 34 are rigidly attached to the body 1 and have ofiset portions 36 which lie substantially parallel with the movable clamping plates 35. Bolts 37 extend slidably through the clamping plates 35 and portions 36 of the clampin plates 34, the heads of the bolts engaging t e inner surface of the clamping plates 35.- Spaced washers 38 are mounted upon each of the bolts 37 outwardly of the portions 36 and expansion spiral springs 39 are coiled about the bolts between said washers, the springs being tensioned by' means of the nuts 40."

The springs 39 urge the plates 35 towards. the parallel portions 36, for clamping the guides 31 and 32 between their respective plates 35 and portions 36 of the plates 34. The yieldability of the plates\35 is provided to-permityaryin of the angular relation between. the com ined handle and pipe 28 and the body 1 during the movement of the machine over a wall or other surface being treated.

Bracket arms 44 are attached to the outer surface of the sides of the body 1 and the have outwardly extending transverse threa ed portions 45 formed thereon upon yvhich nuts 46 are mounted, against which nuts the backs of liquid spreading brushes 47 em connected to a suit;

supply hen e, and a pivotal coup ing connecting age. The backs 48 of the liquid spreading rushes 47 are provided with slots 49 through which the threaded transverse end 45 extend. Inner nuts 50 are mounted on the transverse threaded ends 45 for clamping the brushes against thenuts 46. By ad ustment of the positions of the nuts 46 on the transverse threaded ends 45 the distance between the outersurface of the body 1 and the brushes 47 "may be regulated as desired. The bristles 52 of the brushes project be-. yond the lower edge of the body 1 for spread- 1n liquid over the surface being treated.

preadin plates 55 are mounted, in the corners of t e body 1 outwardly of the guard 2 and near the lower end of the body servin as supports for ball bearing casters or ro lers 56 which are adapted to engage the surface being treated and reduce the friction occasioned by the travel of the spraying machine thereover. It is, of course, to be understood that the invention may be constructed in various other manners. and the parts associated in different relations and, therefore, I do not desire to be limited in any manner except as set forth in the claims hereunto appended.
